Sarah adds 10 g of baking soda to 100 g of vinegar. The mixture begins 20
to bubble. When the bubbling stops, Sarah finds the mass of the resulting
mixture. She determines its mass is 105 g. The data she collected is in the
table. Does this follow the law of conservation of mass? Explain.​

Answers

Answer:

Yes, the reaction between baking soda and vinegar follows the law of conservation of mass.

Explanation:

The table and data was not attached to the question.

When baking soda and vinegar are mixed together, a chemical reaction occur resulting to release of gas (carbon dioxide gas)

Law of conservation of mass states that the total mass of the reactants in a chemical reaction must be equal to the total mass of the products.

That is mass of reactant = mass of product = 100g + 10g = 110g

Sarah got 105g as product because a gas of mass 5g was released during the reaction.

Sarah found the mass of the resulting

mixture without including the mass of the released gas.

A way to account for the mass of the gas is if the experiment is done in a closed system like zip lock bag to collect and account for the mass of the gas.

When this is done, the law of conservation of mass would be proven.

If you stand on the edge of a canyon and shout, you will hear an echo. That is,
some time after you shout, you will hear your shout again coming up from the
canyon. Describe what is happening to the sound of your shout to make this
happen.

Answers

Answer:

The soundwaves bounce off the canyon walls and back to you

Because sound waves bounce off surfaces and rebound, the shout will be reflected back to you. Often, music is captured in a space that is soundproof.

What is Sound wave?

A sound wave is indeed the pattern of disruption brought on by the movement of energy moving through a medium because it propagates away from the origin of the sound (such as air, water, or any other kind of liquid or solid matter). Pressure waves are produced when an object vibrates, such as a ringing phone, and these waves are known as sound waves.

A sound source, like a vibrating speaker's diaphragm in a stereo, produces the sound waves. Vibrations are produced in the medium surrounding the sound source. The medium continues to vibrate as the source does, and as they do, the vibrations move away from where they originated at the sound's velocity, resulting in the formation of the sound wave.

Thus, the shout will be reflected back to you since sound waves bounce off objects and rebound. Music is frequently recorded in a room that is soundproof.

What would happen if a light source was placed below a plant?

• the plant would respond negative to gravity

• the plant would exhibit negative phototropism

• the plant would respond positively to gravity

Answers

The plant would exhibit negative phototropism

A plant would respond positively to gravity if a light source was placed below a plant.

TROPISM:

Tropism is the movement of a plant or part of a plant in response to stimulus (light, heat, water).

A plant's response to light is called phototropism while plants response to gravity is called geotropism.

Ideally, a plant's shoot is positively phototropic while a plant's root is positively geotropic. Hence, if a light source is placed under a plant, the plant would respond positively to gravity.

Answer:

A lunar eclipse occurs when the Earth gets in the way of the sun and blocks sunlight from hitting the moon. This makes the moon have a reddish-orange tint to it. A full moon is visible during a lunar eclipse.

A solar eclipse happens when the moon gets in between the sun and the Earth, forming a crown like ring around the moon, which is from the sun. The moon itself might not be visible, due to the angle at which it sun is hitting it at.

Since the cell membrane is semi-permeable, the likelihood of substance L entering the cell attached to a large protein is lower than that of substance L free in the culture. Substance L enters the cell membrane through active transport, but the cell membrane may block the larger protein, thus blocking substance L, if it is attached to the large protein.
